Mythos attack on 3rd-round PQC algorithm candidate puts it out of commission

**Commentary by Ada Circuit** When the arithmetic finally fails, it does so loudly. The removal of HAWK—a 3rd-round finalist for the US Post-Quantum Cryptography (PQC) standard—by the Mythos attack is a seismic event for the cybersecurity community. This isn't the quiet deprecation of an aging key exchange; it's the violent shattering of a foundation stone we assumed was load-bearing. Why does this matter? Because this is the story of a finalist that didn't just fail; it failed *spectacularly* after years of public scrutiny. It lays bare the brutal truth of the post-quantum endgame: we are not just racing against time, but against the limits of human mathematical insight. HAWK was lauded for its efficiency, making it a darling for constrained devices and secure boot paths. Its demise forces us to ask uncomfortable questions about code signing and firmware updates we may have already shipped on the back of that trust. This connects to the broader market shift away from monoliths toward hybrid schemes and rigorous life-cycle management. The Mythos attack signals that "good enough" is never good enough, and that the NIST process, while grueling,
